Why does my volumetric jet material appear so low res?
For Cycles it was enough to change Mesh to Volume modifier Resolution &gt; Voxel Size to 0.1

For Eevee it is the same, but ...

... you have to change also Render Properties &gt; Volumetrics &gt; End to 1000 m or

... increase Distribution to 0.98 and Tile Size to 4 px

Material is fine.
